Beit known that I, ELennr H. Cannon, a citizen of the United Statesresiding at Worcester, in the county of Worcester and Commonwealth ofMassachusetts, have invented a certain new and useful Improve ment inGuide-Boxes for Rolling-Mi ls, of which the following is aspecification, accompanied by drawings forming a part of the'same, inwhich-5- r Figure 1 is a front elevation pf a rolling mill housingprovided with a guide embody'ing my invention, and F ig. 2'is a sectionon line 2%2, F ig. 1, on an enlarged scale.

Similar reference figures refer to similar 1 parts in the differentviews.

My inventionrelates to a method of supporting the guide box of a rollingmill, by which sutficient resistance to the strains of operation may besecured between the guide box and the sup orting bar, and it consists inthe construc ion and arrangement of pointed out in the annexed claims. A

Referring to the accompanying drawin 1, 1, are theho'usings and 2,2, apair of rolls journaled therein.

3 is a guide box, supported on a bar 4,

which .is attached to the front of the hous ings by bolts 5, 5, andvertically adjustable in slots 6, 6. Guide plates 7 and 8 may be usedwith the guide box, if desired. The

bar 4 extends acrossthe housing and is rovided with longitudinalsurfaces 9 an 10 to receive the. aide box, upon which it is horizontallyadJustableto bring it into alinement with the circumferentialgrooves 11of the rolls. The guide box has at its outer end a depending flange orapron 12, which is provided with a slot 13 for the reception of a bolt14, having a head 15 horizontally adjustable along a longitudinal T-slot16 in the bar 4, having a central opening 17 in the upper side to allowthe bolt 14 to be inserted in the slot 16.

The bearing surface 9 upon the bar 4 for the guide box 3 is locatedat'the inner side of the bar, and the bearing surface 10 is GUIDE-BOXFOB ROLLING-MILLS.

both si es of any possible horizontal axis of rotation. The uppersurface of the guide bar 4.- is also provlded with an'undercut ordovetailed shoulder 18, to receive a corretwistin movement will beprovided upon cal, and thereby provide resistance to the twistingmovement ofthe guide box upon both sides of. any. possible vertical axisof rotation. The ,.c lovetailed shoulders areat an angle to the" planesof the bearing sur faces 9 and 10 ,anfd wlien the guide box is placed inposition "with the dovetailed shoulders 18and 19. engagiii I each other,as shown in Fig. .2, and wit the bolt 14 inserted, the nut 20 istightened to prevent the disengagement of the shoulders 18and 19. a

The movement of the guide box, when the nut 20 is tightened, is also aproximately parallel with the planes of the aringsurfaces 9 and 10, sothat the surfaces 9 and 10 are drawn more tightly into engagement by themovement of the guide .box, controlled by the dovetailed shoulders 18and 19, when the nut- 20 is tightened. The bolt 14 may be made breakableunder undue strain, thereby affording o portunity for the preservationof the guidb box, which is readily detached from the bar 4 moval of asingle nut.

In the strains of ordinary operation, the guide box is held fromliftingby the reby the resistance afforded by the dov'etailedfishoulders 18 and 19, which, arranged at an acute angle to the vertical andextending. the

whole width of the guide box, prevent rotation about a vertical axisrand by the bearing surfaces -9 and 10 which, located at each end of theguide box and equal in length to the width of said box, prevent itsrotation about any intermediate horizontal axis and also prevent thedisengagement of the shoulders 18 and 19 by any strains less than thetensile strength of the bolt 14. As the surfaces 9 and 10 offer apositive resistance to the twist of the guide box as long as thedovetailed shoulders 18 and 19 are in engagement, the strain upon thebolt 14 is entirely longitudinal, all twisting strains being taken bythe bearing surfaces, which enables a comparatively light apron andsmall J sides of said'guidebox in horizontal planes,

tightening of bolt a be used,.which, while or a strength sufficient tohold the guide box under the ordinary operation of the machine,will giveway when subjected to the strain of an acci- I As the flange 12 is drawntoward the bar by tightening the bolt 14,,the bearing surfaces 9 and 10serve to support the guidebox, and the inclined shoulders 18 and 19 havea Wedging effect to draw the guide box against the surfaces 9 and 10.Pressure is, therefore, exerted" between the guide box and all three ofits contacting surfaces by the a single bolt 14. I claim,

1. The combination of a. rolling inill housing, a-guide'su'pporting bar,a guide box mounted on said bar, bearing surfaces on said guide box andsaid bar on opposite thereby preventing the rotation of said guide box'aboutahorizontal'axis, and also bearing surfaces on said guide box andsaid bar in a plane at an acute angle tothevertical, thereby preventingrotation of said 3 guide box about a vertical axis.

2. The combination of a rolling mill housing,- a guide supporting bar, aguide box mounted. on said bar, horizontal bear ing' surfaces on-fsaidguide box and said bar, a longitudinal engaging shoulder at an acuteangle to the vertical on said bar, a'

corresponding engagingshoulder on said guide box,.and means for movingsaid guide.

boxlhorizontally, thereby causing the wedging action of said shouldersand the tighter engagement of said horizontal bearing surfaces.

3. The combination 'of. a guide supporting a "corresponding shoulderarranged to vbe brought into engagement with the shoulder on said bar bya horizontal movement and to cause the approach of said guide 'boxtosaid bar bysaid engagement, af -bolt holdiing said shouldersincngagement, and bear i-ng surfaces between said barandsaid guide boxarranged to prevent during the engagement ofsaid shoulders the rotationto said bar.

of said guide box around'any possible horizontal' axis of rotation. V

- 4. .The combination of a rolling mill housing, a guide supporting bar,a guide box mounted on said bar, said-guide box having a dependingflange at its outer end, said guide bar having horizontal supportingsurfaces for the lower end of said flange and the inner end of saidguide box, and

means arranged horizontally and passing through said flange fordetachably'attaching said guide box to said bar.

5. The combination .of -a rolling mill housing, a guide supporting bar,a guide box mounted on 'said bar, said guide box having a dependingflange atits outer end, said guide bar having horizontalsupportingsurfaces for the lower end of said flange and the inner end of saidguide box, a'horizonta-l bolt passing, through said flange with a headinserted in a slot in said bar, and a nut upon the outer side of saidguide box.

' .6. A rollingmill having aguide box with a depending flange at itsouter end, a guide bar with a horizontal supporting surface for thelower' edge of said flange, a horizontals ppor ng surface for the innerend of said box, bearing surfaces at a slight angle from the vertical onsaid bar and guide'box, and means for impartinga horizontal movement tosaid guide box to bring said angular bearing surfaces into engagement bywhich said guide box iscaused to approach said bar.

7. A rolling mill having a guide box with a depending flange at itsouter end, a guide bar having a supporting surface for the lower end ofsaid flange, and interlocking surfaces on said guide box and said bararranged at a slight anglefrom the vertical, whereby the horizontalmovement of said guide box will draw .said guide box nearer 17th adv ofJune 1908.
